ICE-BUNKER.

SPECIFICATION forming part of Letters Patent No. 223,550, dated January 13, 1880,

Application filed September 19, 1879.

To all whom it may concern Be it known that I, JOHN W. SMITH, of J ersey City Heights, in the county of Hudson and State of New Jersey, have invented a new and Improved Ice-Bunker, of which the following is a specification.

Figure 1 is a rearside elevation of the icebunker. Fig. 2 is an end elevation of the bunker. Fig. 3 is a front elevation, part being broken away. Fig. 4 is a cross-sectional elevation taken through the line no a, Fig. 3.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a bunker for holding ice in markets, hotel provision-rooms, vessels, and other places where a room is to be kept cool, so constructed as to effect a great saving of ice, while keeping the room cooler than the ordinary bunkers.

The invention consists of an ice-bunker havin g frame, casings, inclined bottom, doors, and inlets, as well as outlets, for air, as hereinafter described.

A represents the frame of the bunker, which is supported upon legs or a suitable framework.

The bunker is incased with sheet metal B, wood, or other suitable materiahattached to the inner surface of the frame-work A.

The bottom G of the bunker is inclined, as shown in Figs. land 3, and has a flat surface, so that the ice may lie smoothly upon it, and may thus be prevented from melting so rapidly.

The rear side of the bunker is designed to be placed against the side of the room, and has openings D formed through the upper part of its casing for the admission of air to be cooled. By this arrangement the upright tiin bers of the frame A form passages, through which the air must pass and be partially cooled by contact with the casing B before entering the bunker.

In case the bunker cannot stand against a wall, a casin g should be attached to the outer surface of the rear-side timbers to form the air-passages.

In the middle andlower part of the frontside casin g, B, are formed openings E for theegress of the cold air.

To the outer surface of the frontside timbers of the bunker-frame are attached casings F to form air-passages, which passages are closed at their upper ends, and are provided with doors G at their lower ends, so that they may be opened and closed as may be required.

In the rear end of the bunker is a door, H, through which the ice is put in, and in the lower part of the front end is formed a small door, I, for the egress of cold air. Usually a sufliciently low temperature can be obtained by opening the door I; but when a lower temperature is required, one or more of the doors Gr may be opened.

The side edges of the bottom (3 project beyond the side casing, B, and are slightly bent upward, as shown in Fig. 4, to form shallow channels J, through which dripwater may flow down to the drip apron or spout K at the lower end of the inclined bottom, and pass thence to the waste-water receiver. With this construction any currents of air set in motion by opening and closing the ,door of the room and any inrush of warm air through the open door cannot impinge directly upon the ice, as they can only reach the ice by passing up through the side passages of the bunker, and will thus be checked, so that very little ice will be melted in this way.

Having thus described my invention, what I claim. as new, and desire to secure by Letters Patent, is

The ice-bunker consisting of the frame A, having attached casings F, and thecase B, having openings D E, inclined bottom J, and doors G H, substantially as described.
